A colorimetric test device for monitoring the effectiveness of an ozone-ultraviolet light apparatus for cleaning-stripping work pieces is disclosed. This device relies upon the ability of zone to bring about a color change, typically a bleaching of the color, in various organic dyes. A kit for carrying out the test of an ozone-ultraviolet cleaning-stripping apparatus is also disclosed. This kit includes the test device just described in a premoistened form enclosed in an openable moisture-impermeable container. Test methods using the test device and kit are disclosed.
